I just followed the opt out link and they're making you open a public issue with a Markdown list with all your repositories you want removed.
Surely there has to be a better way to do this (probably the point).
Also why are they storing 4.71 TB in a Git repo? How are they going to deal with removal requests?
EDIT: It seems like they're manually responding to the issues, wtf? There's a perfectly fine GitHub auth system that they could use to verify everyone's GitHub account / repository ownership
EDIT 2: This is apperently a collaboration between Hugging Face and ServiceNow, why is my companies IT ticketing system scraping all of GitHub?
